Confirm cut off of 15ng mean that after they did the original cutoff it was more than 50ng. If the inital cutoff would have been 49ng or less they would have not sent the sample for gs/mc cutoff of 15ng. The second confirmation showed you were 54ng. That is why i said you were so close to passing the first step of 50 ng. Basically like killerweed stated you are fucked.
slantedeyes Reviewed by slantedeyes on . Urine Test Confirm Cutoff/Error Question Knew a test was coming so abstained for 10 days & drank water like crazy. Picked up two home tests from local drug store & both home tests said I passed (negative result). Submitted to official medical test and came up positive by 4ng/mL: Screening Cutoff = 50 ng/mL Confirm Cutoff = 15 ng/mL Confirm Quantity = 54 ng/mL If the confirm cutoff is 15ng, shouldn't a positive need to be at least 65ng (50+15)? Isn't the 15ng the error threshold? If not, what is "confirm cutoff" ? Rating: 5
